Implement Chat Augmentor

Moved a bit of code to base class and added Chat Augmentor implementation.

@mostepaniukvm - Looks great, going to give this a try. Thanks for the MR.

@mostepaniukvm - What are your thoughts on adding a role field and also incorporating the prompt replacement {input} similar to how the other augmentor behaves.

https://git.drupalcode.org/project/augmentor_chatgpt/-/blob/1.0.x/src/Pl...

  if ($role == 'user') {
    $content = str_replace('{input}', '"' . addslashes($input) . '"', $this->configuration['prompt']);
  }
}

Yes, it totally makes sense, pushed additional commit

Added a couple minor tweaks, but tested and this is working great! Going to have some internal team members QA this and we should be good to go to merge. Thanks again for the contribution!

Working great! Short list of what was checked, have it enabled for pages:
- No issues changing the model through ECA
- Basic pages working no errors
- Pages with views no errors
- Pages with blocks and views no errors
- Generate button we have works, no errors
- Only able to test and see user role and it works well
